SPECIFICATION forming part of Letters Patent No. 483,648, dated October4, 1892.

Application filed February 23, 1892. Serial No. 422,543. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN FRIEDRICH FISCH- ER, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in theManufacture of Paper Frames for Slates, 820., which improvement is fullyset forth in the following specification and accompanying drawings.

My invention consists of means, substantially as described, forsimultaneously cutting, striking up, and embossing the paper frames ofslates, pictures, the.

Figure 1 represents a bottom plan view of the cutting, striking-up, andembossing apparatus employed in the manufacture of frames embodyingmyinvention. Fig. 2 represents a horizontal section thereof on anenlarged scale. Figs. 3, 4, and 5 represent sections of different shapesof frames. Fig. 6 represents a perspective view of a slate having aframe manufactured in accordance with my invention.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A design ates the upper cutters, and Bdesignates the upper striking-up and embossing dies, of the apparatusemployed by me, said cutters and dies being placed side by side andalternating.

O designates the lower striking-up and embossing dies, at the sides ofthe working faces of which are cutters D. The lower dies are properlysupported on the base E, and the The cutters and dies are of the form offrames of different sizes and placed one within the other or nested, aswill be seen in Fig. 1. Paper, pasteboard, or paper-stock of suitablenature is placed between the upper and lower parts, and when the sameclose the paper is cut through the shape of a slate-frame andsimultaneously embossed and made semitubular or struck up, it being seenthat the frames produced are of different sizes, and they are incondition to be colored, shellacked,or otherwise coated and finished.The slate is placed between two sections of a frame, and the rims Gthereof are glued or otherwise cemented to each other and to the slate,thus producing a superior frame, the same being strong, light, durable,and inexpensive. The cuttersA of the head are adapted to pass betweenthe dies 0 of the base when the said head is lowered, being in contactwith the cutters D, formed on the edge of the said dies 0.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

Adevice for the purpose named, consisting of the head F and the base E,the dies 0, secured to the base E and having the cutters D on the edges,and the dies B, secured to the head F and having the cutters A betweenthem, said cutters A being adapted to pass between the dies 0, saidparts being combined substantially as described.
